The tablet says network error, what should I do? We solve problems connecting to the Internet via WiFi on Android. Additional methods to solve the problem

Authentication error when connecting to WiFi is one of the most common problems that is associated with a problem connecting the device to the router (router).

Let's take a closer look at the error itself and what to do if it occurs.

Why does this problem occur?

An authentication error occurs when the router and device (connecting subscriber) cannot identify each other for a number of reasons.

The main indicator of such a problem is that when connecting to a network it writes “Saved, not connected” or simply “Saved”.

This problem often occurs both on devices running the Android operating system and on regular personal computers and laptops.

Let's take a closer look at everything possible ways troubleshooting.

Follow the instructions and tips to set up a correct Internet connection.

Password verification

Often the user cannot connect to the network because the password was entered incorrectly.

Due to the fact that the default access window hides the entered password characters, the user may make a mistake and enter one of the characters incorrectly.

Check the “Show password” checkbox to see all the characters you enter.

On computers running Windows OS, hold down the key located on the right in the text field to see the characters of the entered router access password.

If you have forgotten your password, you need to use the router settings.

To do this, follow the instructions below:

Log in using your personal computer or laptop to any of the browsers;
Enter the router's local address in the address bar. Look at the address at the bottom of the router or in its manual. If you do not find localhost information, use the command line.
Turn on the Run window. In the text field, enter "cmd" (without quotes). Press Enter. In the console dialog box that opens, enter the text “ipconfig” (without quotes) and press Enter.
Find the “default gateway” item and look at the address in the column opposite - this is the local identifier of the router on the network;

Enter your login information into the router settings (login and access password). If you have forgotten this information, contact your network provider;
After logging in you will be taken to the tab quick settings router. The settings menu differs depending on the router model. In some cases it may be presented in English;
Go to the advanced settings tab and in the WiFi field, select security settings, as shown in the figure below;

In the encryption key text field, you can open access find out what encryption key the router uses;

Turn off the settings menu and try to connect to the router by entering the access key you just viewed.

Checking the router connection

If after entering the correct password you still get an authentication error, the next step is to check whether the router is properly connected to the network.

The figure below shows a basic router connection diagram.

Make sure all wiring is connected as shown in the figure. Otherwise, reconnect.

After this, reboot all devices and try connecting to the router again.

Also, the problem of authentication error may occur on the provider's side, so it is appropriate to call the telecom provider back.

Perhaps they can solve the problem on their end or send competent specialists to you to solve the problem.

Reinstalling driver software for your computer's network adapter

In some cases, an authentication error occurs on computers with outdated network adapter (network chip) drivers.

Follow the instructions to update your driver software:

Enable the system device manager window. To do this, right-click on the “Start” button and select “Device Manager”;

Find the tab with all devices network adapters and unfold it;

Find your WiFi adapter in the list of devices. Right-click on it and select driver update. The driver software installation process will begin and complete automatically.
Restart your router and computer and try connecting to the network again.

Reflashing the router

To solve the authentication problem, you can try to reflash the router. To do this you need to download new version firmware from the manufacturer's official website.

Typically, the user only needs to enter the driver model and the approximate date of purchase.

To install the software, simply run the downloaded executable file and wait for the installation to complete.

Reboot all devices and try connecting again.

You can also reflash Wi-Fi in its settings menu.

Find the field that shows the version you are using software and click on the update button to begin the process of installing a newer firmware version.

If the problem cannot be solved, you can always roll back the latest one in the router settings installed version software and return the router to factory settings.

However, in this case it is necessary to set again New Password and level of data security.

Setting up router and device encryption

The identification problem may also arise due to the fact that the router and Personal Computer or the user's laptop is used fundamentally different variants network data encryption.

This happens when, during the first setup of the router, inexperienced users set different settings security and encryption.

To troubleshoot the problem, follow the instructions:

Go to your router's settings menu. You can read how to enter the settings in the first instructions of this article;
Go to the security tab and check what encryption mode the router uses when connecting to the computer;

Now enable the computer to router connection window on the desktop toolbar. Select your router from the list of devices and see what encryption technology your PC uses to establish a connection.
If these technologies are different, then in the router settings, change the encryption mode to the one used by the computer. Reboot your devices and connect again. The problem will be solved.
Why does Wi-Fi authentication fail?
Authentication problem when connecting to Wi-Fi networks- This is a very common problem. This can happen for several reasons, which are described in the video presented.

Android Wi-Fi Authentication Problem
Wi-Fi authentication failure on Android is a fairly common problem. As a rule, it is associated with a mismatch in the wireless communication standard.

Often, users have problems connecting to the Internet when the network is active, but the signal is not heard. The device tries to connect to the access point, but the message “WPA protection saved” appears and as a result there is no connection.

Sometimes it happens that the device connects to the network, but in fact the Internet distribution does not work

What to do about it? In most cases, the problems do not concern the phone or tablet, Android devices, but the router itself. There are several ways to change its settings to make it work correctly and have a good connection with your equipment.

Sometimes, to solve a connection problem when “WPA protection saved” appears, it’s enough to reboot Wi-Fi points and reconnect to it. There is probably simply a problem with the router that can be easily fixed by restarting it.

Another one possible reason associated with incorrect operation of the equipment may be due to the fact that its firmware is outdated. Download the most current firmware for the router from the manufacturer’s website and upload the file to the settings menu.

The settings open like this: enter the router’s IP address into the address bar of any browser, enter the value “Admin” instead of the login and password if you have not changed them.

After logging in, update your hardware. Even if the issue is not with the firmware, it is always useful to install a new version once again, because by releasing it, the manufacturer corrects all previous problems.

Regional settings

Access to the network may be unavailable for a trivial reason - the region where you live is incorrectly set in the equipment.

To find out, go to the router settings, select the Wireless section, the Wireless Settings line (for TP-Link brand models) and check which region is indicated in the line with the same name. If the data is incorrect, correct it.

If you have a router of a different brand, look for this data in the section where, in addition to the region, the device name and connection parameters are specified.

Password problems

Checking the correctness of the key

In some cases, the line “WPA Security Saved” appears if you entered the wrong password when connecting. To reset it, click on the network icon, select “Delete”, then reconnect and enter the correct combination.

Changing the password and encryption type

It is likely that the device you are using to connect to Wi-Fi does not understand the password or its encryption type. These parameters can be changed in the hardware settings.

To do this on TP-Link brand models, go to the Wireless menu, select the Wireless Security tab. Here you will change the password - try to create a combination consisting of only numbers. Below, select the encryption method - it is best to select WPA/WPA2 - Personal (Recommended), set the type to AES.

Don't forget to save the changes, reboot and reconnect to Wi-Fi from your gadget. Please note that when you set a new password and change settings, you will need to change the data on the remaining devices that previously connected to this wireless connection.

Changing the operating mode

There is often no connection due to the fact that the phone, tablet or other equipment does not support the router’s operating mode. There are three such modes, all of them are called with Latin letters b, g, n. If the router is set to work in n mode, and the gadget does not support it, then you will not be able to connect them.

Therefore, conduct an experiment: change the way the device operates, for which you must perform the following steps:

Go to the equipment settings, use the previously mentioned Wireless section, Wireless Settings tab.
Stop at the line called Mode.
Now you have to choose a different mode - use the option with all three letters - b, g, n - so that you can connect to Wi-Fi from all devices operating in at least one of these modes.

In ASUS models, you will see such parameters in the “Wireless Network” menu, where there is a tab with a mode selection - stop at the Auto or Mixed option.

Checking Wi-Fi network channels

What else can you do if you don’t have a connection and the message “WPA2 protection saved” appears? Change the channel on which the equipment operates wireless connection to the network.

To do this, do the following:

As you can see, there are many reasons why problems arise with connecting to a network via Wi-Fi, and all of them are mainly related to the settings of the router. If the message “WPA Security Saved” appears, there are several simple ways troubleshoot problems, and you can do this yourself and without any problems.

Many happy owners of tablets actively use Wi-Fi to solve everyday problems. But every now and then, when trying to connect, a Wi-Fi authentication error occurs. The reasons why such a problem occurs usually lie in inattention when entering data, failure of wireless equipment, or incorrect work tablet. Let's consider solution options.

This feature allows you to eliminate unwanted connections to your wireless network.

What is authentication

First, you need to understand that authentication is control of the security key and the method of encoding the transmitted information. This is important so that no one else can connect to the access point in your home. Security options include strong password and the correct encryption standard.

If you have an authentication error, the reasons may be:

Incorrect network access password.
Tablet and router use different types encryption.
Inappropriate communication channels.

The error most often occurs when you enter the password incorrectly. Enter it as carefully as possible. You can check and change the security key in the router settings, where you can also change the channel and encryption. It is possible to change network access parameters without much effort, even for a non-specialist.

Changing your security password

We have already written in detail. In short, you need:

Enter the IP address, login and password of the router in the browser. You can view them on the back or bottom of the device or in the user manual. If you can't find it, enter Win+R - cmd - ipconfig. The “Default Gateway” line displays the router’s address. The default login and password is admin/admin.
Go to the tab Wi-Fi security. In the “Encryption Key” or “Security Password” line, look at the existing one or enter a new password.
On your Samsung or other Android tablet, turn on Wi-Fi, go to Settings - Wireless networks - Wi-Fi - press the name of the connection with your finger - Change this network. Check the “Show password” checkbox and enter it again, carefully checking it with what was entered in the router.

Changing the encryption standard

If the error remains after changing the key, then:

In the router interface, go to “Security Settings”, select the authentication type “WPA-PSK/WPA2-PSK” and encryption “AES”.
On the tablet in Wi-Fi settings hold down the connection name - Delete network. Then connect again.

Changing the Wi-Fi channel

To organize the operation of the wireless network, a frequency of 2.4 GHz is used. To prevent signals from different equipment from overlapping each other, the router is capable of working on 11 channels, automatically selecting the most suitable one. But sometimes there are glitches, the signal gets better, which can cause a Wi-Fi authentication error. To change the channel manually:

Enter the router interface - Wireless network settings.
Check that the region is correctly defined - Russia.
In the “Channel” tab, select one of the 11. Test several times until the tablet connects successfully.

You can check the congestion of each channel using the Free Wi-Fi Scanner for Windows or WiFi Analyzer for Android utilities. Once launched, they will scan all available networks in the room and display the load level of each channel. Choose one that is not loaded at all or is minimally busy.

If all else fails

Although the Wi-Fi authentication error should not occur again once you have completed these settings, in some cases you will have to take more drastic action. You can also try:

Reboot the router. Unplug the power cord, wait half a minute or a minute, then plug it back in.

Reboot the tablet. Especially if it doesn't turn off for a very long time. A simple reboot can sometimes work wonders.
Reset router settings. This can be done through the settings menu in system settings. And if you don’t enter them for a reason forgotten password, on back surface, near the connection ports, there is a small black button. Clamp it with a pin or something sharp, wait a couple of seconds, and then adjust from scratch.
Reset tablet settings. Go to Settings - Personal data - Backup and reset - Reset settings. We hope that you will not have to resort to this step.

Conclusion

Now you are armed with the knowledge of what to do when a problem occurs when trying to connect via Wi-Fi. Do not rush to take your equipment for repair; there are plenty of options for independent solutions. Good luck to you. We will be glad to read your comments with feedback on the material.

Quite often, many users of devices running mobile operating systems encounter an unpleasant situation when the device displays an authentication error when connecting to a wireless network. Such problems can equally be attributed to stationary systems, but it is in them that failures of this kind are much less common. For them, a method for eliminating the problem will be proposed separately, but for now we will focus on Android devices. It is to them that the occurrence of this failure is most often attributed. Accordingly, the proposed methods for eliminating such situations are mainly designed for mobile rather than stationary systems, although they cannot be discounted. But first things first. And first, a few words about the nature of the failure itself, without understanding which all solutions to correct the situation may turn out to be completely ineffective.

What is an authentication error in a general sense?

Let's look not even at the error itself and the nature of its failure, but at the authentication process itself. Don't confuse it with initialization and authorization. These are different things.

Authentication when trying to connect to a WiFi-based wireless network is a check of the key entered for access, or, more simply, the password that is used in the settings of the router or stationary computer device that distributes the signal to prevent unauthorized connection.

The most trivial situation, associated with the appearance of a Wi-Fi authentication error, consists of the usual inattention of the user himself, who enters the wrong combination as a password. In this case, you should go to the network settings, select change parameters and check the box next to the password display line, and after entering, compare it with what is used as the default access key.

Authentication error when connecting to WiFi: reasons for the failure

However, in most cases, this is not the main problem. It may very well be that the mobile device and the router have different types of protection or encryption installed on the data that is transmitted over a secure connection. Sometimes there may be short-term disruptions. It is especially worth noting that the router settings were incorrectly set in terms of selecting the connection type and the channel used. You can deal with all this using completely elementary methods, after which the problem will disappear. Below are several basic techniques.

Checking the current operating mode of the mobile device

So, we assume that when trying to connect to a network, the device generates an authentication error. What to do?

First of all, check the operating mode of the device. Every user should understand that when Airplane mode is activated, absolutely all connections are blocked. It may well be that you were trying to install silent mode by lowering the speaker volume, but accidentally made a longer press, which activated the corresponding “Airplane” mode. Just unplug it and check the connection.

The simplest method to resolve the error

WiFi authentication error on Android, strange as it may sound, can be associated with short-term system failures, especially when you have some kind of optimizer installed that disables everything background services to speed up the device.

Try simply rebooting the device, but do not use a restart for this, but turn off the device completely and turn it on again.

If we talk about home users whose Android system gives an authentication error when connecting to WiFi at home, the problem may also be related to the router itself. Execute full reset its settings by completely turning off the power supply for about ten to fifteen seconds, then turning on the device again. Some experts advise taking a longer pause (up to ten minutes), although, I think, the specified initial period is quite enough.

Difference in encryption systems

Let's understand a little about what an authentication error is. Now a few words about the most common reasons for its appearance. The problem is that the router and mobile device may use different types of selected security systems.

Very often this problem occurs with mobile devices model range Samsung Galaxy. The router is set to WPA-PSK Personal by default, and the phone is using WEP. This mismatch causes the device to generate a WiFi authentication error.

Router setup questions

Thus, eliminate this problem You can set the correct parameters on both the router and the mobile device.

On the router you can use automatic settings, and as additional means select mixed connection mode (11b/g or 11b/g/n). Typically these settings are located in the wireless section. Wireless connections. Yes, here's another thing. Don’t forget to check whether distribution is enabled on the router, otherwise the Internet connection indicator may blink, the provider’s router will be detected by external ping, but there will be no connection and there will be no connection.

Setting a priority channel on the router

There is another common problem related to the settings of the used channels allocated for connection. In this case, a failure message may also appear. What is the authentication error in this case? Nothing more than the inability to connect via an automatically selected communication channel.

To fix the problem, log into the router’s web interface through any browser installed on a desktop computer system (for example, in Windows), and in the corresponding settings item, alternately select the use of one of the eleven available channels, saving the settings and checking connectivity.

Pairing setup

Finally, one of global solutions interconnection problems mobile technology with routers or stationary distribution devices, is to establish pairing with standard IP protocols of the fourth and sixth versions. You need to set such options specifically on a smartphone or tablet.

The sixth protocol, apparently, will not have to be used, since in the post-Soviet space there are not many providers using DHCP servers of the sixth version. Therefore, you can limit yourself to pairing with IPv4.

Windows Solutions

But so far everything described has applied mostly to mobile systems. You shouldn't forget about Windows either. This is especially true for situations when a distribution server is installed on a computer or laptop.

As a rule, the IPv4 settings indicate automatic acquisition of addresses of all types, but often the problem may be that the system cannot convert standard requests to domain name into a digital combination, for which DNS servers are responsible.

To fix the problem, try simply changing the Preferred and Alternate settings DNS server, setting the parameters in the form of free Google combinations (options with eights and fours).

Sometimes, if distribution is not taking place, it is necessary to call the services section (services.msc in the “Run” menu), find DNS and DHCP clients there, check their status (they must be active with the priority set to “Running”). If the services are stopped, you should go into editing options (double-click or RMB menu), press the start button to start them manually and set the startup type to automatic. After completing all actions and saving the settings, the computer system should be rebooted without fail, and after the restart, check the possibility of connecting via WiFi.

Another common problem is blocking of incoming and outgoing connections on the created server by installed standard antiviruses and Windows firewall. At least, the occurrence of such situations is very often associated with the Avast package.

To fix the problem, disable your antivirus for ten minutes and check the connection. If it works, get rid of this software. If there is no effect, deactivate the Windows Firewall.

If you suspect exposure to viruses, use portable scanners like KVRT or Dr. Web CureIt, but it is best to check the system before starting the download using disk applications like Kaspersky Rescue Disk. The uniqueness of such utilities is that when writing to removable media, you can use the built-in bootloaders, select a graphical interface and scan computer system before Windows boot. Such tools are not provided for mobile systems (unfortunately).

The maximum that can be used is mobile antiviruses or programs that disable all unnecessary services like Root Booster. Such applications, however, will require superuser rights, but the effect of increasing productivity cannot be compared with anything. In practice, this particular utility has shown itself to be the best.

Instead of a total

In general, if we summarize what an authentication error is, it should already be clear. And you shouldn’t associate its appearance solely with mobile systems. As follows from the material presented above, if there are distribution devices based on a virtual server for Windows systems, the occurrence of such a failure is also no exception. As for troubleshooting, of course, you should start with the settings of the router and mobile device, since the same types of protection systems may not match. Otherwise, the proposed solutions can be used exactly in the order of their description, although in most cases it can be quite difficult to name the true cause of the failure, especially since the error message itself almost never indicates anything particularly specific about the description. And this is precisely the biggest disadvantage, because of which it is simply impossible to initiate a failure.

Perhaps the most common problem that occurs on a phone or android tablet- authentication error when connecting to home Wi-Fi. In order to eliminate it, you need to understand the basic principles of the device’s operation, as well as know what authentication is and why it is not performed.

What is authentication

You cannot solve a problem without understanding its essence. Wi-Fi authentication is the process of verifying a security key. In simple words- coincidence set password networks with the one entered by the user. the main task authentication on your phone or tablet - protect your network from unauthorized access.

Not every user understands that any devices connected to a single Wi-Fi network can easily exchange data. This is why open Internet connection points are considered unsafe. In order to connect to a wireless network without fear for the safety of your data, an authentication process was invented. The most common way to authenticate a user is to prompt them for a password.

How does authentication work?

The user connects to the network, then enters the security key;
an Android tablet or phone encrypts the entered information and sends it to the router;
the router decrypts the data;
depending on their compliance or non-compliance, denies or allows the user to connect.

This is why if you enter the password incorrectly, an error occurs. In this case android device writes that you were unable to complete the authentication process, and your phone or tablet does not connect to the Internet.

Steps to connect to wireless Internet

Before connecting to a wireless network, make sure that the wifi module on your Android phone or tablet is turned on. For this:

go to your phone settings;
go to the wireless networks menu;
if your phone or tablet tells you “to see available networks, turn on wifi,” then move the slider at the top to the right position.

After a few seconds, a list of available wireless networks will appear here. If you see a “lock” next to the wifi icon, then you will need to go through an authentication process to connect.

enable the “show password” feature

Decide which wireless network you want to connect your mobile phone or tablet. Click on it. After this, a dialog box will appear on the display of your device with its name, information about the signal level, type of protection and a field for entering a password (if it is protected). In order not to make a mistake in entering it, scroll down the dialog box and check the “show password” box.

This way you will see exactly what characters you are entering. After entering the appropriate password combination, click the “connect” button. The phone or tablet will report that it has successfully connected to the selected wifi network or an error will appear.

Main problems

It often happens that when entering incorrect password and trying to connect to a wireless network, a phone or tablet under its name, instead of the “connected” message, writes: “Saved, protected by WPA2” (WPA2 is the type of network used, so it can change). Then there are several authentication attempts and eventually the message “authentication error” or “network connection error” (which is basically the same thing) appears. In such a situation, the user has basic questions: what to do and why does the error appear?

There are three most common problems that prevent a phone or tablet user from android base go through the authentication process:

incorrectly typed password for connecting to wifi (security key);
mismatch between the router data encryption type and the settings on your phone or tablet;
wifi router malfunction.

Depending on the type of problem, the ways to solve it vary.

Incorrect password

Click on the name of the wireless network that is giving you an authentication error. After opening a small dialog box, select “delete”. Don’t worry, it won’t disappear anywhere, but will appear again in this list, after which you can repeat the operations performed by entering the correct password. Don't forget to check the "show password" checkbox. Double-check the key carefully. Users often confuse the symbol zero with the letter “o”, one with the Latin “i” and “l”, the capital letter “I” (i - “ai”) and the small “l” (L - “el”), and so on. Don't forget that the password may be case sensitive (small and UPPERcase letters).

If you are sure that the entered password is correct, but your phone or tablet is operating system Android still gives this error, turn off the Wi-Fi module and turn it on again, trying to connect to this network again, or completely restart the mobile device and try to connect again.

Faulty router

Also, the problem may lie in the router itself that distributes the Internet. In this case, you can try to connect to others wireless networks, other routers. For example, to free Wi-Fi in restaurants, shops, etc. If the problem persists, then most likely you will have to completely reset your smartphone to factory settings. At the same time, do not forget to do backup copy information stored on your android phone or tablet, otherwise you will lose it.

Data encryption type mismatch

The error may appear due to a data encryption type mismatch or a mode unknown to the device wifi networks. The problem is resolved by changing their types. To do this, you need to connect to the router (via Wi-Fi or using a cable) and enter the router settings. Enter in address bar IP browser of the access point (this information can be found on the case, box or in the instructions of the router).

How to find out the IP access points through the Network and Sharing Center

- open the “Network and Sharing Center”;

- find the line “connection” and select “wireless network connection”;

- in the dialog box that opens, click on the “details” button;

- “default gateway IP v4” is the IP of the access point to the router.

Changing the encryption type in the router settings

After entering the IP access point in the browser, you will be taken to the router settings, where you will need to enter a login and password (default: admin, admin). Depending on the manufacturer and model, the program interface may differ.
